If you still haven’t made it to San Francisco’s second-most-popular attraction (the first is cable cars), you might want to start planning that vacation before long. It’s possible that Alcatraz, that formidable white structure hunkered out in San Francisco Bay, might be converted into an international peace center, if voters so choose.

Although the idea sounds pretty far-fetched, Da Vid and volunteers were able to collect the 10,350 signatures needed to put the proposition on the ballot.%Gallery-15480%
